An operator in the Orinoco heavy oil belt in Venezuela realized an additional 150 ft (46 m) of pay using the Dielectric Scanner service. The production potential of the laminated reservoir could not be determined accurately with conventional logs because thinly bedded sand and shale layers decreased resistivity measurements and masked pay zones. The result was a pessimistic interpretation of the hydrocarbon volume. The scanner provided important information about the reservoir quality of the lower interval, revealing movable oil over a 150-ft section. Sidewall samples confirmed the measurements.
